"This project was part of the City of Winnipeg's continuing program to dispose of sewage sludge in an efficient, economical and environmentally sound manner. The primary objective of the study wasto assess the environmental impact of sub-surface injection of rawsewage sludge into agricultural soil. The determination of the types and numbers of pathogenic organisms in raw sludge and their fate in heavy clay soils was examined as were the types and quantities of organic micropollutants and their fate in agricultural soil. A secondary objective of the study was to assess the impact of anaerobically digested sludge injected into agricultural soil. An additional objective was to inject sludge using a production model injector to determine practical application rates under full-scale operation"--Abstract.
